PLEASE combine the awesome, fast 3D of Flyover with the street-level vantage point of Street View! That sounds like what this is.
Agreed. The worst part of Flyover is the trees. They look like crap and block the road, which is the information you are looking for. Combine street level 3D LIDAR scans with existing overhead LIDAR scans and you have a really compelling immersive mapping environment. 3D overhead views with the ability to remove trees (or make them transparent) so you can see the underlying roads perfectly. Zoom down to street level and smoothly navigate the street without waiting for tiles to load.
The data could also be sold for gaming and filmmaking purposes. High end film companies often require high resolution LIDAR scans of cities so they can destroy them in CG.
Or, while you're driving they can overlay the scan data perfectly on top of the real world view though your heads up display. Augmented reality car navigation.
This is a smart move by Apple. It takes what Google has to the next level. And Apple is ahead this time because they already have the overhead 3D scans.
